花穗修剪方式对“夏黑”葡萄产量与经济效益的影响

Effects of Floral Cluster Pruning on Fruit Qualities of Summer Black Grape

以"夏黑"葡萄为试材,研究了不同花穗整形方式对葡萄产量、果实品质和经济效益的影响,筛选适宜的花穗整形方式,以期为我国葡萄标准化生产提供参考依据。结果表明:不同的花穗整形方式对产量、果实品质存在一定影响。圆锥形整形花穗长度4.5 cm的处理能显著增加果粒纵横径、单粒质量、可溶性固形物含量,降低可滴定酸含量。在"夏黑"葡萄生产中,选择圆锥形整形花穗长度4.5 cm的标准化花穗整形方式。

‘Summer Black’grape was used as material,different treatments of floral cluster pruning on fruit qualities and economic benefits were studied,the suitable floral cluster pruning way was screened in order to supply reference for standardized production of grape.The results showed that the treatments of panicle modes flower only leaving spikelet tip 4.5 cm significantly increased the every berry weight and the total soluble solids content and they all significantly decreased the titratable acid content,the better comprehensive quality,so this kind of floral cluster pruning might be fit for flower management in‘Summer Black’grape.
